What is the backlight on a tv? craftsman 19.2 volt hammer drill There are a handful of high-end TVs that use full-array LED backlighting in a slightly different way, which we'll discuss later.

While the backlight control adjusts the overall output of the LED array that makes up the set’s backlight, the brightness control is used to adjust black level, or how dark the dark areas of the picture appear onscreen. The set’s contrast control, on the other hand, is used to adjust the intensity of the lightest areas of the picture, or the highlights. So to answer your main question, yes, a TV’s backlight control can dim the screen’s intensity without compromising pic. The main difference between the Edge Lit LED TV and the Backlit appearance is the thickness of the television. While an Edge Lit is pretty thin and skinny, the Backlit is a bit bigger. To some people this doesn’t matter much, but to others this difference in appearance makes all the difference.  Direct Backlit - This is the older LED backlight technology from which edge LED's evolved mostly due to cost and size i.e. slimness requirements. Direct Backlit's tend to be on the thicker side. Altough theoretically they should be better than edge, actually they aren't because most of these are quite old and don't have more modern picture processing / upscaling advantages besides they also lack in absolute brightness compared to edge LED's. Local dimming is a feature on LED TVs that dims the backlight behind parts of the screen that are displaying black. This makes blacks appear deeper and darker.
